How to use loop control to populate Json array

[sniperwolfpk5]

Hello @sfmskywalker

I want to use loop (Foreach, while or any) control to populate signal array. Workflow steps are

1. Use Receive HTTP Request with the follwing data
   { "WFId": "WF1", "Name": "Qamar", "Email": "[email protected]", "Receiver":"[email protected]", "Body": "This is a sample document.", "Actions": [ { "Name":"Approved", "ActionUrl":"" }, { "Name":"Rejected", "ActionUrl":"" }, { "Name":"Withdraw", "ActionUrl":"" } ] }
2. then using loop control to poputla ActionUrl
3. then using Write HTTP Response with poulated ActionUrls
   { "WFId": "WF1", "Name": "Qamar", "Email": "[email protected]", "Receiver":"[email protected]", "Body": "This is a sample document.", "Actions": [ { "Name":"Approved", "ActionUrl":"http://localhost:56583/workflows/signal?token=CfDJ8LzCQns8bxpBjTuZdgBTx3lTl6TxwffP8IWE_KssIfWMWNn9ZYk6LkrM6OAZtOMPhjmrhfLQ0vAYSrZ0VWFO7qXprK_UeRw4U_hzTVKRu9DG_OPSfS1dBYwK6HXJc_FOeNl1HlCdXca-qxmfoOGoQaHsC-owSRmMv2rdpM3gc7x9-f2B-K2M2RigV0c0v9JOQl6sXDvssXvPj89ZvqSSKhU" }, { "Name":"Rejected", "ActionUrl":"" }, { "Name":"Withdraw", "ActionUrl":"" } ] }

Please note I want to use dashboard.

I can do it by hard coding but I do not want that route.

Appreciate your help

I tried to use javascript but the resulting data is empty. Please have a look to attached workflow

@sfmskywalker
Can we use javascript code in JavascriptExpression? I mean loops, functions, expressions etc.

Hi @sniperwolfpk5 ,

Unfortunately, there are currently no activities available that would allow you to do that:

• The SetVariable activity only allows setting a value to a variable, whilst you'd need a way to set a value to a value within a variable.
• There is no activity that allows you to run a script.

I think the best way to implement your requirement is to have a RunScript activity as described in this issue.

Then you could write a for each loop in e.g. JavaScript and update the model to your heart's content.
